In certain circumstances the information_schema columns are lowercased from the db. This updates the mysqlSerializer to handle this case.
Fixes #3884
I suspect this may be a MariaDB vs MySQL difference, but I haven't confirmed it.
In my case (mariadb:10.11 docker) only the
table_constraints
andcheck_constraints
tables' columns are lowercased, so I haven't updated the code for eg.INFORMATION_SCHEMA.STATISTICS
orinformation_schema.referential_constraints
.
